To be fully compliant with all applicable Intel SDRAM memory specifications, the board should have DIMMs that support the serial presence detect (SPD) data structure. If your memory modules do not support SPD, you receive a notification to this effect on the screen at power up. The BIOS tries to configure the memory controller for normal operation.

Intel® Desktop Board DX58SO has four 240-pin DDR3 DIMM sockets arranged in three channels (A, B, and C). Channel A shares two sockets (DIMM 0 and DIMM 1) and Channels B and C have one socket each.

32-bit operating systems are limited to a maximum of 4 GB of memory. The operating system reports less than 4 GB because of the memory used by add-in graphics cards.
